Woodward PEAK200-HVAC 8200-1501 Steam Turbine Control
Key Features and Advantages:
The Woodward 9907-1200 revolutionizes turbine control with its 10 µs loop update rate, enabling sub-cycle response to grid frequency fluctuations. Adaptive combustor dynamics modeling automatically compensates for fuel quality variations, reducing NOx emissions by up to 15% in gas turbine applications.
Cybersecurity resilience: Featuring FIPS 140-2 validated encryption and role-based access control, the 9907-1200 protects against cyber threats in networked turbine arrays. The integrated WebMonitor™ interface provides 3D vibration spectrum analysis and predictive maintenance alerts via machine learning algorithms.
For offshore environments, the controller’s conformal-coated PCB withstands 98% humidity and salt fog exposure. Hot-swappable I/O modules allow field replacements without turbine shutdown, while its backward compatibility with legacy 505E systems simplifies upgrades in aging power plants.
Application Areas:
The Woodward 9907-1200 excels in:
- Combined heat and power (CHP) plants: Optimizing steam-to-power ratios in real time
- Pipeline compressor stations: Preventing surge in centrifugal compressors during load transients
- Marine propulsion: Synchronizing twin turbines for dynamic positioning systems
- Geothermal plants: Managing flash steam turbines in high-H₂S environments
In aerospace test facilities, the 9907-1200 controls turbine rigs with 0.01% speed accuracy for FAA certification tests. Its SIL 3 certification makes it indispensable for safety-critical shutdown systems in LNG liquefaction trains.
